ClassLink Roster Server is built using an application layer and a database layer to ensure reliability and security. The web application is hosted in the cloud on reliable and redundant hardware. Keeping the application in the cloud means we can always keep it current.
The database layer, which holds all your student data, is hosted on a dedicated OneRoster database server in the cloud with limited access. This means only you and the people you share it with have access. Vendors will gain access to your data via REST API or CSV templates based on the orgs and class permissions provided.
We strongly recommend ClassLink to host your Roster Server - a hosted server can be set in 5 minutes or less!
The OneRoster spec can be found on the IMS Global website.
The CSV template specification can be found here.

|> 10,000 < 100,000||4 GB||2 VCPUs||40 GB|
|> 100,000 < 250,000||8 GB||4 VCPUs||80 GB|
|> 250,000||16 GB||4 VCPUs||80 GB|
